Research on carbon fiber material for reinforcement and repair of concrete structures began in the 1980s in developed countries like the U.S. and Japan. China's entry into this technology was late, but with the rapid development of our country's economic construction and transportation, a considerable number of existing buildings have historical issues due to low design load standards at that time. Some buildings, with changes in usage functions, struggle to meet current code requirements, and urgent repairs and reinforcement are needed.

Currently, there are many commonly used reinforcement methods, such as: increased cross-sectional method, encased steel reinforcement method, bonded steel reinforcement method.Carbon Fiber ReinforcementCarbon fiber reinforced repair structure technology is a new type of structural reinforcement technique following the increase in concrete cross-section and steel bonding.
